A ranking table tennis system

ranking-table-tennis

Ranking system for table tennis players.

The system keeps a record of championship points and rating points.

Championship points aim at tracking the tournament achievements of players. Their computation is based on the best rounds reached by players in each tournament.

Rating points aim at tracking the relative skill level of players. Their computation is based on the outcomes of one-versus-one matches.

Usage

The commands must be run in a bash terminal. Use uv run ... if you have installed with uv.

1. Fill a sheet with the tournament matches. It must be saved in the Tournaments spreadsheet (xlsx).

   Players and Initial Ranking sheets must be in the same spreadsheet (it is used as a database).

2. Run rtt preprocess.

   The scripts will read the Tournament spreadsheet and will ask for missing information of new players (city, affiliation, initial rating points, and category). This information will be saved in the Players and Initial Ranking sheets.

3. Run rtt compute.

   It will ask for the tournament that you want to process. 0 will compute all from the beggining. The outcome will be saved in the Ranking spreadsheet.

4. Run rtt publish.

   It will ask for the index of the tournament that you want to publish. The outcome will be saved in a new spreadsheet.
